+# Cross-Platform AES-Encrypted Payload Injector
+
+This project provides secure AES-CBC encrypted payload injection for both Windows and Linux platforms.
+
+## Features
+
+- **AES-128-CBC Encryption**: Industry-standard encryption with proper key derivation
+- **Cross-Platform**: Separate binaries for Windows and Linux with no code leakage
+- **Embedded Payloads**: Encrypted data embedded directly in executables
+- **Secure Key Derivation**: SHA256(password + salt) with random salts and IVs
+
+## Compilation Instructions
+
+### Linux Build
+
+```bash
+# Compile Linux injector
+g++ -std=c++11 linux_injector.cpp -o linux_injector -lssl -lcrypto -ldl
+
+# Test (requires encrypted payload data)
+./linux_injector
+```
+
+### Windows Build
+
+```bash
+# On Windows with Visual Studio, compile:
+cl.exe /EHsc windows_injector.cpp advapi32.lib
+
+# Or with MinGW:
+g++ -std=c++11 windows_injector.cpp -o windows_injector.exe -ladvapi32
+
+# Test (requires encrypted payload data)
+windows_injector.exe
+```
+
+## Usage Instructions
+
+### 1. Encrypt Your Payload
+
+```bash
+# Encrypt a binary (DLL/SO) with the Rust crypt tool
+cd crypt
+cargo run /path/to/your/payload.dll
+
+# This creates:
+# - encrypted_Input.bin (encrypted payload)
+# - decryption_metadata.bin (salt + IV + size)
+```
+
+### 2. Embed Encrypted Data
+
+Edit the appropriate injector file (`linux_injector.cpp` or `windows_injector.cpp`):
+
+```cpp
+// Convert encrypted_Input.bin to hex array
+xxd -i encrypted_Input.bin > payload.hex
+
+// Convert decryption_metadata.bin to hex array  
+xxd -i decryption_metadata.bin > metadata.hex
+
+// Replace the placeholder arrays in the injector code
+const unsigned char encrypted_payload[] = {
+    // Copy from payload.hex
+};
+
+const unsigned char decryption_metadata[] = {
+    // Copy from metadata.hex
+};
+```
+
+### 3. Set Password
+
+```cpp
+// Change the password in the injector
+std::string password = "YourSecureMasterPassword123!";
+```
+
+### 4. Recompile and Deploy
+
+The injector will:
+1. Decrypt the embedded payload using AES-CBC
+2. Inject the decrypted library into a target process
+3. Execute silently
+
+## Security Features
+
+- **AES-128-CBC**: Prevents pattern analysis attacks
+- **Random IVs**: Each encryption uses unique initialization vectors
+- **PKCS7 Padding**: Proper padding with validation
+- **SHA256 Key Derivation**: Password-based key generation with salt
+- **No Embedded Keys**: Keys derived from passwords, not stored
+
+## Architecture
+
+- **Rust Crypt Tool**: Encryption with AES-GCM fallback to AES-CBC
+- **C++ Decryptor**: Standalone decryption utility
+- **Platform-Specific Injectors**: Windows (DLL) and Linux (SO) injection
+- **Embedded Payloads**: No external file dependencies
+
+## Testing
+
+Both platforms have been tested with:
+- ✅ Encryption/decryption workflow
+- ✅ Binary integrity verification
+- ✅ Cross-platform compilation
+- ✅ Platform-specific injection techniques
+
+The Linux version uses ptrace-based injection, while Windows uses advanced NT API techniques with job objects and APC queuing.
